Does anyone know the case cap of the 375 Ruger case & how it compares to the 300WM?
According to Quickload, the 375 Ruger holds 99gr of water, the 300WM holds 88-95.5 depending on brass. Quickload lists 300WM (W), 300WM (N), 300WM (R), 300WM (F), 300WM (@). It shows 300WM (N) as 95.5 and 300WM(R) as 88, the other are in between.
